3) When drain hose requires extension, obtain an extension hose commercially
available.
Be sure to thermally insulate the indoor section of the extension hose.
4) When connecting a rigid polyvinyl chloride pipe
(nominal diameter 13mm) directly to the drain
hose attached to the indoor unit as with
embedded piping work, use any commercially
available drain socket (nominal diameter 13mm)
as a joint.
